Benefits of technology

The present invention provides a flame resistant exhaust filter apparatus, system, and method that can effectively filter grease-laden vapor or air from kitchen equipment. The filter assembly is disposable and easily replaceable, reducing the need for costly and time-consuming cleaning of traditional filters. The filter assembly is also formed from flame resistant viscose, which is strong and self-supporting, and may reduce or eliminate damage to the filter assembly in situations in which it comes into contact with extreme heat, open flames, or grease flare-ups. The technical effects of the present invention include efficient removal or reduction of grease particulate matter, improved fire barrier, ease of removal and replacement of grease-saturated filter assembly, and reduced likelihood of damaging fire caused by flames interacting with grease build-up in traditional filters.

Problems solved by technology

The exhausted air in the food preparation environment is typically laden with greasy vapor and unwanted odors and substances.
In addition, the grease and others substances contaminate the hood and fan and these require constant cleaning to remove the grease.
Moreover, the grease in the ducting constitutes a major fire hazard as ducting fires are a constant concern.

Embodiment Construction

[0019]FIG. 1 illustrates a particular embodiment of an exhaust filtration system 10. Exhaust filtration system 10 may include vent hood 20 and filter assembly 30. To filter grease, vapor and other particulates arising from kitchen equipment, filter assembly 30 may be mounted in vent hood 20. In particular embodiments, filter assembly 30 may be formed of materials such that it is generally “self-supporting,” meaning that it does not require metal filter support frames, frame covers or heat shields. Filter assembly 30 can be formed in a variety of ways using a variety of materials that may result in a filter assembly 30 that is either reusable or disposable. In such embodiments, filter assembly 30 may be easily mounted, as discussed further below, in vent hood 20 by simply sliding it into place on brackets or some other similar fastening or support system within vent hood 20.

[0020]Vent hood 20 may represent any ventilation equipment designed or configured to exhaust heat, odors, greas...

Abstract

A filter assembly includes a filter pad comprising flame resistant viscose. The filter assembly also includes a bonding emulsion. The bonding emulsion may comprise casein resin. The bonding emulsion may additionally comprise acrylic resin. The filter assembly also includes a structural support. In particular embodiments, at least a portion of the fibers are treated with a solution that is fire resistant or fire retardant.

Description

RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 60 / 099,688, filed Sep. 24, 2008, U.S. Provisional Application No. 61 / 099,699, filed Sep. 24, 2008, and U.S. application Ser. No. 12 / 430,650 filed Apr. 27, 2009, which are each incorporated herein by reference.TECHNICAL FIELD OF THE INVENTION[0002]The teachings of the present disclosure relate generally to exhaust filtration in ventilation systems, and more particularly to a flame resistant viscose filter apparatus and method.BACKGROUND OF THE INVENTION[0003]The exhaust units used in food preparation and commercial kitchens include devices such as air extractor hoods and air conditioning units. The traditional exhaust systems include filter elements that use a variety of metal or flame listed baffles, as identified in the various U.S. or State Codes, for the purpose of blocking flames from penetrating the exhaust system and diverting grease from building up in the ductwork of the exhaust...
